In the embodiment, the firstdriving circuit 120 is, for example, a data driving circuit, and thesecond driving circuit 130 is, for example, a gate driving circuit, butthey are not limited thereto.

The first signal lines FSL and the second signal lines SSL arerespectively configured to transmit signals to the pixels P. Withreference to FIGS. 1C and 1D, the extending direction of the firstsignal lines FSL is different from the extending direction of the secondsignal lines SSL, and the first signal lines FSL and the second signallines SSL are disposed intersecting one another on the substrate 110.The first signal lines FSL extend in the direction from the firstdriving circuit 120 to the display region DR, and the second signallines SSL extend in the direction from the second driving circuit 130 tothe display region DR. In the embodiment, the first signal lines FSLare, for example, data lines, and the second signal lines SSL are, forexample, gate lines, but they are not limited thereto.

The function module 140 generally refers to a module element capable ofrealizing various different functions. For example, the function module140 is a camera module, a light intensity sensing module, a sound wavetransceiver module, or other modules with different functions. Thecamera module is, for example, a module having a photographing function.The light intensity sensing module is, for example, an optical sensingmodule that senses the light intensity of an external light beam. Thesound wave transceiver module is, for example, a module capable oftransmitting sound waves or sensing sound waves.

In another embodiment,the imaging module Len is a lens array, that's to say, a plurality ofoptical lenses arranged in an array, and the disclosure is not limitedthereto.

The following paragraphs will describe in detail the dispositionpositions of the first active elements T1 and the second active elementsT2, the circuit layout among the pixels P, the specific structure ofeach pixel P, the circuit layout in each pixel P, and the dispositionrelationship between the first pixels P1 and the camera module 140 a.

First, the disposition positions of the first active elements T1 and thesecond active elements T2 will be described first.

With reference to FIG. 1D, in the embodiment, the first active elementsT1 are disposed outside the first display region DR1. More specifically,the first active elements T1 are disposed between the first displayregion DR1 and the second display region DR2 and are dispersedlydisposed around the first display region DR1 for example. From anotherpoint of view, the orthographic projection regions of the first activeelements T1 on the substrate 110 do not overlap the first display regionDR1. In other words, there are no active elements T in the first displayregion DR1.

With reference to FIGS. 1C and 1D, on the other hand, the second activeelements T2 are disposed in the second display region DR2. Morespecifically, the second active elements T2 are respectively disposed inthe second pixels P2.

Next, the circuit layout among the pixels P is described.

In order to describe the circuit layout among the pixels P, the criteriaof grouping the first signal lines FSL and the second signal lines SSLhave to be described first. The first signal lines FSL are divided intoa plurality of groups according to the electrical connectionrelationship with the first active elements T1, the second activeelements T2 and the first driving circuit 120. The second signal linesSSL are also divided into a plurality of groups according to theelectrical connection relationship with the first active elements T1,the second active elements T2 and the second driving circuit 130. Thespecific electrical connection relationships will be described in thefollowing paragraphs.

With reference to FIGS. 1C and 1D, the first signal lines FSL aredivided into first-group first signal lines FSL1 and second-group firstsignal lines FSL2, and the main difference is that the first-group firstsignal lines FSL1 are electrically connected to the at least one firstactive element T1 and the first driving circuit 120. The second-groupfirst signal lines FSL2 are respectively electrically connected to apart of the second active elements T2 and the first driving circuit 120.

In addition, the second signal lines SSL are also divided intofirst-group second signal lines SSL1 and second-group second signallines SSL2, and the main difference is that the first-group secondsignal lines SSL1 are electrically connected to the at least one firstactive element T1 and the second driving circuit 130. The second-groupsecond signal lines SSL2 are respectively electrically connected to apart of the second active elements T2 and the second driving circuit130.

With reference to FIG. 1C, FIG. 1C shows the circuit layout of thesecond-group first signal lines FSL2 and the second-group second signallines SSL2.

The second-group first signal lines FSL2 extend in a direction D1. Thesecond-group second signal lines SSL2 extend in a direction D2. Thedirection D1 is perpendicular to the direction D2. Each of thesecond-group first signal lines FSL2 is electrically connected to thefirst driving circuit 120 and electrically connected to thecorresponding second pixel P2. Each of the second-group second signallines SSL2 is respectively electrically connected to the second drivingcircuit 130 and electrically connected to the corresponding second pixelP2.

With reference to FIG. 1D, FIG. 1D shows the circuit layout of thefirst-group first signal lines FSL1 and the first-group second signallines SSL1.

The respective vertical projections of the at least one first activeelement T1 and the first-group first signal lines FSL1 between thesecond display region DR2 and the first display region DR1 on thesubstrate 110 overlap each other. Specifically, the number of the firstactive element T1 is a plurality. The first active elements T1 arerespectively electrically connected to the first pixels P1. Thedisposition positions of each of the first active elements T1 or atleast a part of the first active elements T1 correspond to thefirst-group first signal lines FSL1. The meaning of “dispositionposition correspondence” as used in this paragraph is that each of thefirst active elements T1 or at least a part of the first active elementsT1 overlap the first-group first signal lines FSL1 in the verticaldirection VD; that is, the projected area of the first active elementsT1 projected on the substrate 110 in the vertical direction VD and theprojected area of the first signal lines FSL1 projected on the substrate110 in the vertical direction VD have an overlapping region. In detail,the projected area of the first active elements T1 on the substrate 110completely or partially overlap the projected area of the first signallines FSL1 on the substrate 110. Then, wirings are extended from thefirst active elements T1 individually to be electrically connected tothe first pixels P1 in a one-to-one manner. It should be noted that, inorder to simplify the drawings, the wiring extending from a single firstactive element T1 in the first display region DR1 is illustrated as oneas an example, which is only used to illustrate the electricalconnection relationship as an example, and the number of the wiring maybe two or a plurality in practice. The vertical direction VD isperpendicular to the directions D1 and D2 or is the normal vector of thesubstrate 110.

The respective vertical projections of the at least one first activeelement T1 and the second-group first signal lines SSL1 in a region ofthe second display region DR2 adjacent to the first display region DR1on the substrate 110 overlap each other. Specifically, the first activeelements T1 are respectively electrically connected to the first pixelsP1. The disposition positions of each of the first active elements T1 orat least a part of the first active elements T1 correspond to thesecond-group first signal lines SSL1. The meaning of “dispositionposition correspondence” as used in this paragraph is that each of thefirst active elements T1 or at least a part of the first active elementsT1 overlap the second-group first signal lines SSL1 in the verticaldirection VD. Then, wirings are extended from a part of the first activeelements T1 to be electrically connected to the first pixels P1 in aone-to-one manner.

Therefore, in the display apparatus 100 in the embodiment, the firstdriving circuit 120 and the second driving circuit 130 can beelectrically connected to the first and second active elements T1 and T2through the circuit layouts of the first-group and second-group firstsignal lines FSL1 and FSL2 and the first-group and second-group secondsignal lines SSL1 and SSL2 to further control the first pixels P1 andthe second pixels P2 to display the image.

Based on the above, in the embodiment, the first active elements T1 arelocated outside the first display region DR1, whereby the lighttransmittance of the first display region DR1 is greatly improved. Inaddition, since the second pixels P2 in the second display region DR2are respectively disposed with the corresponding second active elementT2, the transmittance of the second display region DR2 is lower than thetransmittance of the first display region DR1.

In the embodiment, the signal lines for connecting the first pixels P1in the first display region DR1 also connect the second pixels P2 in thesecond display region DR2—that is, the signal lines of the two displayregions DR1 and DR2 are shared. In other word, a signal lineelectrically connects both display region DR1 (active element T1) anddisplay region DR2 (active element T2). In other embodiments, the signallines of the two display regions DR1 and DR2 are not necessarily shared,and the disclosure is not limited to the above. That is, a signal lineelectrically connects only display region DR1 (active element T1) andanother signal line electrically connects only display region DR2(active element T2).

Next, the specific structure of each pixel P and the circuit layout ineach pixel P are described.

In the embodiment, the structure of the first pixels P1 disposed in thefirst display region DR1 is different from the structure of the secondpixels P2 disposed in the second display region DR2. The followingparagraphs will first describe the difference between the first pixelsP1 and the second pixels P2.

With reference to FIGS. 1D and 1E, the first pixels P1 include aplurality of first sub-pixels SP1 (exemplified with three firstsub-pixels SP1) and a transmission region TR. The second pixels P2include a plurality of second sub-pixels SP2 (exemplified with threesecond sub-pixels SP2). Since the first pixels P1 further has thetransmission region TR compared with the second pixels P2, thetransmittance of the first pixels P1 is higher than the transmittance ofthe second pixels P2.

With reference to FIG. 1F, in order to describe the specific structuresof the first pixels P1 and the second pixels P2 of the substrate 110,only a first sub-pixel SP1R in the first pixels P1 and a secondsub-pixel SP2R in the second pixels P2 are used as an example fordescription here. The other first sub-pixels SP1G and SP1B in the firstpixels P1 are similar to the first sub-pixel SP1R. In addition, theother second sub-pixels SP2G and SP2B in the second pixels P2 aresimilar to the second sub-pixel SP2R.

In detail, the first sub-pixel SP1R is disposed on a substrate SB and agate insulating layer GI, and the first sub-pixel SP1R includes a redlight emitting element, insulating layers I1 and I2, and a pixeldefining layer PDL.

In the embodiment, the type the light emitting element disposed in thefirst sub-pixels SP1 is, for example, an organic light emitting diode(OLED). Specifically, the red light emitting element includes a lightemitting layer EL, an electrode layer A1, and an electrode layer A2. Thelight emitting layer EL is interposed between the electrode layer A1 andthe electrode layer A2, and the electrode layers A1 and A2 areelectrically connected, wherein the electrode layer A1 is, for example,a cathode, and the electrode layer A2 is, for example, an anode, butthey are not limited thereto. The electrode layers A1 and A2 areelectrically connected to a first sub-active element ST11 through awiring. The material of the light emitting layer EL is, for example, anorganic light emitting material and is, for example, an organic lightemitting material that emits red light after electroluminescence.

The insulating layers I1 and I2 are disposed between the red lightemitting element and the gate insulating layer GI.

The pixel defining layer PDL is also referred to as a pixel definitionlayer, which exposes a region where the first sub-pixel SP1R forms thelight emitting layer EL. Moreover, the pixel defining layer PDL isfurther configured to separate the light emitting layers located in theother first sub-pixels SP1.

In addition, the transmission region TR is disposed nearby the firstsub-pixel SP1R. In the embodiment, a light transmitting material isdisposed in the transmission region TR, which is, for example, air or alight transmitting material but is not limited thereto. Further, in FIG.1F, the transmission region TR is disposed with the substrate SB and isnot disposed with other layers. In other embodiments, one to a pluralityof insulating layers or light emitting layers or the like is selectivelydisposed according to process requirements. It should be noted that thetransmission region TR is not disposed with a layer that lowers thelight transmittance. For example, the transmission region TR is notdisposed with a metal layer (such as a cathode of an organic lightemitting diode). Specifically, in the embodiment of FIG. 1F, each layer(such as the insulating layer, the light emitting layer, the metallayer, etc.) forms an opening in the transmission region TR, therebyincreasing the transmittance of the transmission region TR (relative toother regions), but the disclosure is not limited thereto; in othermodified examples, a part of the insulating layer is still disposed inthe transmission region TR, and the light emitting layer and the metallayer form an opening in the transmission region TR, so that thetransmission region TR includes the substrate SB and an insulating layer(such as the gate insulating layer GI, the insulating layer I1, theinsulating layer I2, etc.).

The structure of the first sub-pixel SP1R and the transmission region TRhas been roughly described so far. The structures of the first sub-pixelSP1G and the first sub-pixel SP1B are inferred by analogy, and thedifference is that the material selected for the light emitting layer ELcorrespondingly disposed therein is an organic light emitting materialwhich can emit green light and blue light after electroluminescence.

The difference between the second pixels P2 and the first pixels P1 ismainly that the second pixels P2 are not disposed with the transmissionregion TR. Moreover, the structure of the second sub-pixel SP2R in thesecond pixels P2 is similar to the structure of the first sub-pixelSP1R, and the difference is that the second sub-pixel SP2R furtherincludes a second sub-active element ST21.

The second sub-active element ST21 is, for example, a thin filmtransistor (TFT) including a channel layer CH, a gate G, a source S, anda drain D. The channel layer CH, the gate G, the source S and the drainD are stacked and disposed on the substrate SB. The gate G iselectrically connected to the corresponding second signal line SSL(belonging to the second-group second signal lines SSL2) and iselectrically connected to the second driving circuit 130 through thesecond signal line SSL. The gate G overlaps the channel layer CH, andthe gate insulating layer GI is interposed between the gate G and thechannel layer CH. The source S and the drain D are located on thechannel layer CH and are electrically connected to the channel layer CH.The source S is electrically connected to the corresponding first signalline FSL (belonging to the second-group first signal lines FSL2) and iselectrically connected to the first driving circuit 120 through thecorresponding first signal line FSL.

The second sub-active element ST2 is exemplified by a thin filmtransistor of a bottom gate type, but the disclosure is not limitedthereto. In other embodiments, the second sub-active element ST2 is athin film transistor of a top gate type or of other types. In addition,the structure of the first sub-active element ST1 is similar to thestructure of the second sub-active element ST2, and details are notdescribed herein.

Next, the insulating layers I1 and I2 are disposed between the red lightemitting element and the second sub-active element ST2. A via holefilled with a conductive material penetrates through the insulatinglayers I1 and I2, and one end of the via hole is connected to theelectrode layer A2, and the other end of the via hole is connected tothe electrode layer A1.

The structure of the second sub-pixel SP2R has been roughly described sofar. The structures of the second sub-pixel SP2B and the secondsub-pixel SP2G are inferred by analogy, and the difference is that thematerial selected for the light emitting layer EL correspondinglydisposed therein is an organic light emitting material which can emitgreen light and blue light after electroluminescence.

In addition, in the above embodiment, the type the light emittingelement is exemplified by an organic light emitting diode, but thedisclosure is not limited thereto. In other embodiments, the types ofthe light emitting element are changed to a mini LED or a micro LED,wherein the size of the mini LED, for example, falls within a range of100 micrometers to 200 micrometers, and the size of the micro LED is,for example, a micron-level size, and the size thereof is, for example,less than 100 micrometers and greater than 0 micrometers; the disclosureis not limited to the above. The size of the above-mentioned lightemitting diode is defined by, for example, the length of the diagonal ofthe top view of the light emitting diode, and the disclosure is notlimited thereto. In other words, the embodiments of the disclosure isnot necessarily configured to drive the organic light emitting diode andis configured to drive light emitting elements of other different types.

It should be noted that each of the first pixels P1 mentioned aboveincludes the plurality of first sub-pixels SP1 and the transmissionregion TR. The first sub-pixels SP1 include red, green, and blue lightemitting elements and the second sub-pixels SP2 of each of the secondpixels P2 include red, green, and blue light emitting elements. That is,the type of the first pixels P1 described above is an RGBT type, and thetype of the second pixels P2 is an RGB type. In other embodiments, thefirst pixels P1 are not disposed with the transmission region TR butinclude another first sub-pixel having a white light emitting element inthe region of the transmission region TR of FIG. 1E instead; that is,this embodiment includes four first sub-pixels, and the type of thefirst pixels P1 is an RGBW type. Alternatively, in an embodiment, thefirst pixels P1 are not disposed with the transmission region TR; thatis, the type of the first pixels P1 is the RGB type.

Lastly, the disposition relationship between the first pixels P1 and thecamera module 140 a is described.

With reference to FIGS. 1B and 1D, in the embodiment, the camera module140 a is disposed nearby the back side BS of the display apparatus 100and correspondingly disposed on the back surface of the first displayregion DR1 on the substrate 110. Since the first display region DR1 hashigh transmittance, the camera module 140 a can capture the externallight beam correspondingly and sense the image. In other words, thefirst display region DR1 has a good light collecting effect. At the sametime, the display apparatus 100 also control the first pixels P1 locatedin the first display region DR1 and the second pixels P2 located in thesecond display region DR2 to display the image. Therefore, the displayapparatus 100 of the embodiment can realize a high screen-to-body ratiodesign.

In other embodiments, the camera module 140 a is replaced with afunction module with other functions, and the disclosure is not limitedthereto. For example, if the camera module 140 a is replaced with alight intensity sensing module, the light intensity sensing module isrelatively easy to sense the external light beam.

It is to be noted that the following embodiments use the referencenumerals and a part of the contents of the above embodiments, and thesame or similar reference numerals are used to denote the same orsimilar elements, and the description of the same technical content isomitted. Reference may be made to the foregoing embodiments for thedescription of the omitted part, and details are not described herein.

FIGS. 2 to 7 are enlarged schematic views of different embodiments ofthe region B in FIG. 1A. It should be noted that a part of the firstsignal lines FSL and the second signal lines SSL are omitted in FIGS. 2to 7 for clarity in illustration.

With reference to FIG. 2, the layout of the first active elements T1 andrelevant wirings of FIG. 2 is different from that of FIG. 1D, and themain difference is that in FIG. 2, the first display region DR1 has afirst side S1 and a third side S3 opposite to each other, which are, forexample, an upper side and a lower side, respectively. The first displayregion DR1 has a first symmetry axis SA1 with respect to the first sideS1 and the third side S3. The first symmetry axis SA1 is perpendicularto the extending direction D1 of first signal lines FSL. The firstactive elements T1 are disposed on the first side S1 and the third sideS3 of the first display region DR1 according to the first symmetry axisSA1. More specifically, the first active elements T are disposed on theboth two sides S1 and S3 of the first display region DR1, for example,according to the first symmetry axis SA1 and in a symmetrical way. Inother embodiments, the first active elements T1 are not necessarilydisposed in a symmetrical way; for example, the first active elements T1are dispersedly disposed around the first display region DR1, or thefirst active elements T1 are collectively disposed in a region outsidethe first display region; one of ordinary skill in the art can changethe disposition positions of the first active elements T1 according todesign requirements, and the disclosure is not limited to the above.

In addition, in the embodiment, the first active elements T1 aredisposed to overlap the corresponding first signal lines FSL (not shownin FIG. 2). In this way, the aperture ratio of the second display regionDR2 can be less affected.

With reference to FIG. 3, the layout of the first active elements T1 andrelevant wirings of FIG. 3 is similar to that of FIG. 2, and the maindifference is that in FIG. 3, the first display region DR1 further has asecond side S2 and a fourth side S4 opposite to each other, which are,for example, a left side and a right side, respectively. A part of thefirst active elements T1 (i.e., the eight first active elements T1located on the upper and lower sides) are disposed on the first side S1and the third side S3 of the first display region DR1 according to thefirst symmetry axis SA1. The other part of the first active elements T1(i.e., the four first active elements T1 located on the left side) aredisposed on the second side S2 of the first display region DR1. However,the fourth side S4 is not disposed with the first active elements T1. Inother embodiments, the first active elements T1 are evenly distributedand disposed around the first display region DR1 or are collectivelydisposed in a region outside the first display region DR1, etc., and thedisclosure is not limited to the above.

With reference to FIG. 4, the layout of the first active elements T1 issimilar to that of FIG. 1D, and the main difference is that in FIG. 4,the first display region DR1 further has a second side S2 and a fourthside S4 opposite to each other, which are, for example, a left side anda right side, respectively. The first display region DR1 has a secondsymmetry axis SA2 with respect to the second side S2 and the fourth sideS4. The second symmetry axis SA2 is perpendicular to the extendingdirection D2 of the second signal lines SSL. At least a part of thefirst active elements T1 (the first active elements T1 other than thethree first active elements T1 on the leftmost side in FIG. 4) aresymmetrically disposed on the second side S2 and the fourth side S4 ofthe first display region DR1 according to the second symmetry axis SA2.The other part of the first active elements T1 (i.e., the three firstactive elements T1 on the leftmost side in FIG. 4) are further disposedon the second side S2 of the first display region DR1. In addition, eachof the first active elements T1 is disposed on the corresponding secondsignal line SSL of the first-group second signal lines SSL1. In thisparagraph, the meaning of so-called disposition with correspondence isthat a part of the first active elements T1 overlaps the second signallines SSL in the vertical direction VD, and thus the first activeelements T1 can less affect the aperture ratio of the second displayregion DR2. Then, wirings are extended from the first active elements T1individually to be electrically connected to the first pixels P1 in aone-to-one manner.
